Title: Culture of micro-organisms on hydrocarbons
IPC: C12P13/14
Filed: 1969-04-30
Abstract: 1,223,946. Glutamic acid, inosine, by fermentation. ASAHI KASEI KOGYO K.K. 30 April, 1969 [8 May, 1968], No. 22081/69. Heading C2C. [Also in Division C6] A culture of bacteria or yeast is grown in a culture medium of hydrocarbons as the main carbon source, which culture medium initially comprises at least one straight chain C 14 -C 18  paraffin hydrocarbon and to which are thereafter added C 8 -C 18  hydrocarbons of a wide carbon number range necessarily including at least one component in the range C 8 -C 13 . Examples are directed to the production of (i) L-glutamic acid by growing Corynebacterium petrophilum (ATCC 19080) on hexadecane and C 8 -C 13  n-paraffins (subsequently added), Corynebacterium hydrocarboclastus (ATCC 21402) on hexadecane and C 10 -C 13  n-paraffins (subsequently added) and Corynebacterium oleophilus (ATCC 21403) on C 14 -C 18  n-paraffins and C 9 -C 18  n-paraffins (subsequently added), and (ii) inosine by growing the adenine-less mutant Corynebacterium petrophilum ATCC 21404 on hexadecane and C 10 -C 13  n-paraffins (subsequently added). Further examples relate to the cultivation of Candida petrophilum (ATCC 20226) on hexadecane and C 10 -C 13  n-paraffins (subsequently added) and Candida tropicalis on hexadecane and C 9 -C 16  n-paraffins (subsequently added).

Title: Improvement in vibrator circuit
IPC: H02M7/62
Filed: 1945-08-28
Abstract: 598,006. Electromagnetic interrupters. PLESSEY CO., Ltd. Aug. 28, 1945, No. 22087. Convention date, Sept. 1, 1944. [Class 38(v)] [Also in Group XXXV] In a system in which the load is shared by two vibratory interrupters, the two vibratory reeds are maintained in synchronism by the driving means of each including a driving coil operated by contacts on that reed and a control coil energised in phase with the driving coil of the other interrupter. The two similar vibrating interrupters A, B have reeds 10, 10<1> carrying contacts 12, 121 and 13, 131 which engage contacts 14, 14<1> and 15, 15<1> to connect battery 26 alternately to the halves of centre-tapped primaries 23, 24 of three limbed transformers 22, whereby A.C. is induced in the centre-tapped secondary 25, which may be converted to D.C. at terminals 29 if desired by rectifier tubes 27, 28. The driving means comprise main coils 16, 16<1> shortcircuited when contact is made between 12, 14 and 12<1>, 14<1>, but the field due to 16 is slightly weakened by a smaller coil 17 which is connected in parallel with and energised synchronously with coil 16<1>, while coil 17<1> bears a similar relationship to coil 16<1> and 16. When the two vibrators operate in synchronism, coils 16, 161 drive the reeds normally with a slightly reduced flux, but when vibrator A leads, coil 17 remains energised after coil 16 has been shortcircuited, and suppresses the flux more quickly so that reed 10 slows down. When vibrator A lags, coil 17 is de-energised before coil 16, the field is strengthened and reed 10 speeds-up. As similar effects operate on vibrator B the two reeds 10, 10<1> always tend to remain in synchronism.

Abstract: 952,200. Thermionic engines. BROWN, BOVERI & CIE A.G. June 23, 1960 [Sept. 15, 1959], No. 22102/60. Heading H1D. [Also in Division G6] In a nuclear reactor electricity is produced directly by thermionic emission from the surface of a fuel element to a collector electrode, the space between the fuel element and the collector electrode being evacuated. Fig. 1 shows a fuel element which may be inserted in a reactor of known construction. The fuel 1 is enclosed in a jacket 2 of electron-emitting material and is surrounded by an anode 3, the inside surface of which is polished to reflect heat and the exterior of which is cooled, for example by a rare gas flowing through the passage separating the anode from the moderator 4. The space between the anode and cathode may be evacuated to a pressure of about 10<SP>-2</SP> mm. by a pump (not shown) connected to the head 11. The base 14 of the fuel element rests on a current collector 15 set in an insulating ring 17 mounted in the supporting grid 6 of the moderator structure. At the top of the fuel element is a current collecting ring 9 connected to the anode 3. Each fuel element may comprise a number, e.g. three, of thermionic cells connected in series, the cathode 2 of one cell being connected to the anode 3 of the next cell with insulating rings 12, 13 provided at the connection and also serving as distance rings. The electron-emitting material may be thorium, barium impregnated with tungsten, calcium deposited on tungsten, or carbides such as titanium or zirconium carbide, or oxides such as ThO 2 , BaO/SrO, or silicides.

Title: Improvements in tools for joining metal strips
IPC: B65B13/18
Filed: 1925-09-04
Abstract: 262,185. Signode, Ltd, (Consolidated Steel Strapping Co.). Sept. 4, 1925. Jointing by stamping.-In a tool for joining metal strips, such as the overlapping ends of package binders embraced by a sleeve, of the type having a pair of power-operated deforming jaws, the source of power is utilized both for applying and loosening the tool and is controlled by a trigger or like member. The jaws are connected by links 2 to a cylinder 4 which is reciprocated on a fixed core 5 by compressed air admitted to the tool through a union 9. The operation of the tool is controlled by a slide valve 11 which may be pressed down by a trigger 12 on the handle 10 against the action of a spring 13. When the trigger is pressed down air is supplied to the exterior of the cylinder by way of a lateral opening 22 in the hollow interior of the valve neck 14 and passage 16 and the cylinder is thus pushed forward, air in the space 8 being put into communication with the exhaust by passages 21, 18 and the neck 15 of the valve. When the trigger is released, air passes from the lateral opening 22 through passages 17, 20 to the space 8 to return the cylinder, the front end of which is exhausted through passage 19 and neck 15. The tool may be operated by water under pressure or by electrical power in which latter case a trigger switch is used. Specification 22114/13 is referred to.

The bar 49 comprises three tubes 51, 52, 53 which can be selectively collapsed into the base of the frame 33, the various conveyer discharge positions being selected by locking the tubes in extended, partly-extended or collapsed position by removable transverse bars. Extension-limiting rods, are provided within the telescopic tubes. The forward end of the conveyer is supported on the truck walls through grooved rollers 26, its rear end being pivoted to a turntable 24 on the machine 10 beneath the discharge hopper 21 of the bucket conveyer 18. The height of the scarifier 70 and brush 14 is adjustable and rear ploughs 10 on each side of the machine 10 are adjustably positioned by hydraulic rams.

Abstract: 1,010,535. Electric selective signalling systems. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 29, 1964 [June 26, 1963], No. 22275/64. Heading G4H. A character, selected by displacing a combination of input bars 6, 7, 8, 9, 10, Fig. 1, is both punched 6 and printed 5 on a tape 1. The input bars 6, 7, 8, 9, 10 directly control corresponding punches 15, 16, 17, 18, 19, and, by means of coded patterns of apertures 36, they allow one of ten levers 3 to close a single contact 37 corresponding to the digit entered. When a continuously rotating type wheel 62 is in the appropriate position to print the entered digit, a thyratron 57 fires, via the closed contact 37 and a rotary switch 53, to energize a solenoid 60 and thereby print the entered digit by the side of its punched representation. Depending upon the relative positions of the punches and the printing head, it may be necessary to advance the tape between the two operations in order to achieve the desired sideby-side relationship between the printed and punched representations of the entered digit. In a second embodiment (Fig. 2, not shown) up to 48 different characters can be printed and punched using six or seven-hole tape and each entered character causes two of the contacts 37 to close.
